All this cant keep up with the WR if he tries to locate the ball stuff is B.S. J.J does it fine, Aaron Glenn did it fine, Reeves, Aso, All top notch CBs can keep looking back trying to locate the ball and not lose his WR. But yet KJ cant ?!?!?!?

Hmmm do we need to hang a handy cap sign on the front of his helmet since he cant do what all the greats can do.

Common sense would tell you that once you quit watching the receiver, you are at a disadvantage in regards to reacting to his movements. Common sense.

The greats in man coverage understand timing. They understand when to turn around and quit reacting to the receiver in order to locate the ball to make a play on it. They look for tells in regards to how long the play as lasted for, the receiver's eyes, his footwork, etc to determine when is best to turn and locate. That's the main difference between Kareem Jackson and the great man coverage corners in this league.

Some guys have it immediately, some guys take more time to develop it, some guys never do. I think Kareem has shown an ability to grow and learn in his short time here. I have confidence that he will get better at it. He will never be "one of the greats" in man coverage. Those are the types that understand it immediately. Take Revis or Aso for example.

Kareem is a great tackler and, as Rey said, is very good when the play is in front of him. He isn't going to let a receiver run a slant and break his tackle to go 25+ very often. He consistently makes that tackle and keeps it at 10 yards or less. That's very important in the NFL.

People that expect Kareem to be "one of the greats" just because he was a first rounder are unrealistic in their expectations. It's doubtful that he will ever be at that level.
